The launch's burst did not enter its first screen exactly once: its
firstScreen mark ran count times. 0 when the burst ended without it;
1 when it ran once but the entry did not complete (the burst caught the
entry's failure, Effect.ignore included, or the fiber was interrupted
before the screen was assigned); 2 at the second run, which fails at once.
A defect of the declaration; the launch is rolled back.
cause is the entry's own failure when it failed and the burst swallowed it,
so a count of 1 never hides the real error (a ScreenDataError, a
network failure); absent when the mark never ran or a caught failure was not
the reason.
